How do I add a Filter?

Hey guys,

How would i add a filter to an EA, so that it will only trade if the signal bar occurs on increasing volume, relative to the previous bar?

Thanks!

if (Volume[0] > Volume[1]){......make trade......}

This is if the signal bar that you refer to is the current one.

If it is the previous bar then :

if (Volume[1] > Volume[2]){......make trade......}
